How is it possible to detect the filling of a bottle under a water tap by hearing the sound at a distance?

उत्तर
As the water level in a bottle kept under a water tap rises, the length of air column decreases, so the frequency of sound produced increases i.e., sound becomes shriller and shriller. Thus by hearing sound from a distance, one can get the idea of water level in the bottle.
